How is it remotely possible that 1 in 4 Texans believe Obama is a Muslim?

His father was muslim so people automatically say he was a muslim. He was NOT raised muslim, his father left his family when Barack was a baby and he saw him for a month when he was 10 and that was it. He is Church-of Christ. People can be so ignorant. I live in Texas and I am voting for Obama. If people did an ounce of research they would know that.
